A 2-year-old male is brought to the pediatrician by his parents, who are concerned because they have noticed that one of his testicles seems to be missing from the scrotum.
Upon examination, the doctor confirms that the right testicle is not palpable in the scrotal sac.
The left testicle is present and normal.
The parents are informed about the risk factors associated with this condition.
What condition is most likely being described?

Choice A rationale

Pediculosis, an infestation of lice, is highly contagious through direct contact, especially head-to-head contact. Therefore, no precautions are insufficient to prevent the spread of lice to healthcare workers and other patients. Standard precautions are necessary.

Choice B rationale

Wearing a gown and hair cover is not typically required for routine care of a child with pediculosis. Standard precautions, including gloves to prevent direct contact with the child's hair and scalp, are generally sufficient. Gowns are usually indicated when there is a risk of contact with body fluids or secretions.

Choice C rationale

Isolating the child in a negative-pressure room is reserved for airborne infections, such as tuberculosis or measles. Pediculosis is transmitted through direct contact, not airborne droplets, so isolation in a negative-pressure room is unnecessary and inappropriate.

Choice D rationale

Wearing gloves is the appropriate nursing action when treating a hospitalized child with pediculosis. Gloves prevent direct contact with the lice and their eggs (nits) during examination and treatment of the scalp and hair, thus minimizing the risk of transmission to the healthcare worker. .

Choice A rationale

Myoclonic seizures are characterized by brief, sudden, involuntary muscle jerks or twitches. These movements are typically not associated with a complete loss of postural tone leading to a fall. The child's presentation of suddenly dropping to the floor without warning indicates a loss of muscle strength.

Choice B rationale

Atonic seizures, also known as drop attacks, involve a sudden loss of muscle tone, causing the individual to fall abruptly. This loss of tone can be localized or generalized, affecting the entire body, which aligns with the description of the child suddenly dropping to the floor.

Choice C rationale

Absence seizures are characterized by brief lapses of consciousness, often appearing as a staring spell. Individuals usually do not fall during an absence seizure; instead, they may have subtle motor movements like eye blinking or lip smacking.

Choice D rationale

Tonic seizures involve a sudden increase in muscle tone, causing stiffening of the body, arms, or legs. While a person might fall due to the rigidity, the primary characteristic is muscle stiffening, not a sudden loss of tone.
